Technical Documentation Generator FAQ

Is the technical documentation generator free?

Yes, with no sign-up. It runs on your own OpenRouter account; free models cost nothing.

Will it invent endpoints or API keys?

It writes from what you describe and uses clear placeholders like {BASE_URL} and YOUR_API_KEY where details are missing. Review before publishing.

Can I paste the docs into Confluence, Notion or GitBook?

Yes. Copy keeps headings, tables and code blocks, or download the Markdown file.

Which model works best for technical docs?

Larger models write more accurate code examples. Small models are fine for user guides.

Is my product information private?

There is no server. Your text goes from your browser straight to OpenRouter and the result stays in your browser.
